Hyperextension: A hydrogen‐bonded, dimeric capsule can be expanded with four, eight, or twelve glycoluril spacers (see picture) that increase the cavity's volume by up to 530 Å 3 and its length by up to 21 Å. The extended assemblies are chiral and encapsulate a variety of normal alkanes. The expanded capsules suggest that increasingly complex capsules may emerge from other spacers with hydrogen‐bonding capabilities and curved surfaces.
